edit: Sources say the player is Jovan Belcher. Police have yet to confirm.

An unnamed Kansas City Chiefs player has committed suicide at the team facility and authorities are on the scene, the police confirmed to ESPN on Saturday morning.

Local reports say police are operating with the belief the player fatally shot his girlfriend at a house before driving to Arrowhead Stadium and killing himself at around 8 a.m local time. The Associated Press reported the player's age to be 25.

"We can confirm that there was an incident at Arrowhead earlier this morning," the Chiefs said in a statement. "We are cooperating with authorities in their investigation."

There were no other injuries at the team facility, police said.

The Chiefs (1-10) were preparing to host the Carolina Panthers on Sunday.

The NFL has told the Panthers to travel as planned to Kansas City on Saturday, the Charlotte Observer has reported, citing interim general manager Brandon Beane.

Aren't players a bit more tightly knit group of people? Especially the "starters". I guess people are never used to thinking about what other people say and think people are joking when they say "oh I would be better off dead".

I can see a practice squad person or someone who doesn't hang around with people slipping through the cracks and no one seeing or talking to them and this could happen a bit easier. I guess it is hard to fathom something like this with no signs or red flags or anything that might have popped up.
